Curriculum Vitae

Department(s): Cellular Biology and Pharmacology

Barry P. Rosen is currently Distinguished University Professor at the Herbert Wertheim College of Medicine, Florida International University in Miami, Florida since 2009. He was Associate Dean for Basic Research and Graduate Programs from 2009-2016. For 22 years he was Chair and Distinguished Professor of Biochemistry and Molecular Biology at Wayne State University School of Medicine in Detroit, Michigan. He received his B.S. from Trinity College, Hartford, Connecticut in 1965 and his M.S. (1968) and Ph.D. (1969) from the University of Connecticut and was an NIH postdoctoral fellow at Cornell University (1969-1971). He was on the faculty at the University of Maryland School of Medicine in Baltimore, Maryland for 15 years. For nearly four decades his laboratory has investigated the mechanisms of transport and detoxification of transition metals, heavy metals and metalloids in bacteria, yeast, protozoans, mammals and plants. He identified the pathways of arsenic uptake, efflux, biotransformation and regulation in organisms fromE. colito humans. He identified most of the known arsenic detoxification genes and characterized their gene products at the biochemical and structural level. He solved the crystal structure of the ArsA As(III)-translocating ATPase, the ArsR repressor orthologue CadC, the ArsC and LmAcr2 arsenate reductases, the ArsH NADPH-FMN oxidoreductase, the ArsD As(III) metallochaperone, the ArsM As(III)-SAM methyltransferases fromCyanidioschyzon merolae and Chlamydomonas reinhardtiiand most recently the ArsI C-As lyase. He identified and named the ArsR family of metalloregulatory proteins. He made the seminal discovery that aquaglyceroporin channels, fromE. coliGlpF to human AQP9, are the transporters that nearly every cell uses to take up As(III). He is currently elucidating the enzymes and transporters of the arsenic biomethylation and organoarsenical redox cycles. He has published more than 320 papers, reviews and books and is the holder of a prestigious MERIT Award from the National Institute of Health. He is recipient of numerous awards, including Basil O'Connor Award from the March of Dimes, Maryland Distinguished Young Scientist Award, Josiah Macy, Jr. Faculty Scholar Award, Gershenson Distinguished Faculty Fellow Award (WSU), Outstanding Graduate Mentor Award (WSU) and Lawrence Weiner Medical Alumni Award (WSU) and is an elected fellow of both the American Association for the Advancement of Science (AAAS) and the American Society for Microbiology (ASM). He has been on many national and international panels at NIH, NSF, and American Heart Association, and on multiple editorial boards. He has served as both President of the Wayne State University Academy of Scholars and President of the Association of Medical and Graduate Departments of Biochemistry. He most recently was a reviewer of the FDA policy on arsenic in rice.

Research Interests:
Pathways of arsenic uptake and detoxification (NIH Grant R37 GM55425)
The overall goal of research in the Rosen laboratory is a detailed molecular analysis of the arsenic transporters and modifying enzymes.Arsenic, a Group 1 human carcinogen, ranks first on the EPA's Superfund list. Arsenic enters the human body from both geological and anthropogenic sources. Because of the ubiquity of arsenic in the environment, every organism has developed transport systems for the efflux and detoxification of arsenic. Chronic exposure to arsenic has been linked to cardiovascular and peripheral vascular diseases, neurological disorders, diabetes and various cancers. Arsenic-containing drugs are used as chemotherapeutic agents for the treatment of leukemia and parasitic diseases. An understanding of both arsenic chemistry and the molecular details of arsenic transport systems is essential for alleviating the problems of arsenic toxicity, as well as for the rational design of drugs to treat drug-resistant microbes and cancer cells.
